My first exposure to RAL was working as a consultant for a European fenestration company in the US ( ecowindowsusa.com). I got to know the color wheels intimately. The European uPVC, Aluminum and wood windows and doors are out of this world in terms of performance and features. It seems everyone liked RAL 9005 ( Black ) or RAL 7016 ( Anthracite grey ). As a curious fact, it turns out that Poland is a world leader in window manufacturing, with a 16.1% share of global exports and an average export value that increases 18% per year.
